Short answer: no. This Is Not a Murder Mystery is invented. Nobody was murdered at an English country house full of Surrealists. But the show borrows a lot from real life: most of its suspects are real artists, the 1936 London exhibition they’re preparing for really happened, and their aristocratic host is based on a real patron of Surrealism. The six-part series starts on Acorn TV on Monday, October 12, 2026, with one new episode a week.
No spoilers here: this covers the history, not who the killer is.
What the show is
The series is a Belgian production, made mostly in English. Christophe Dirickx and Matthias Lebeer came up with it, and Dirickx wrote it with Paul Baeten. Panenka and Deadpan Pictures produced it, and it first aired on Belgium’s VRT 1 in October 2025. It’s set on a grand English estate in the 1930s, where a group of ambitious young Surrealists end up trapped with a serial killer while two Scotland Yard detectives, played by Stephen Tompkinson and Donna Banya, investigate. Those two detectives are fictional. The show was filmed in Ireland and Belgium in 2024, not in England.
Real people in the cast of characters
Most of the artists are historical figures, played by little-known actors. The director preferred newcomers, so famous faces wouldn’t distract from the characters. They include:
- René Magritte (Pierre Gervais) and his wife Georgette
- Salvador Dalí (Iñaki Mur) and his wife Gala
- Man Ray, Max Ernst, Lee Miller, Paul Nash, E.L.T. Mesens and Pablo Picasso
- Sheila Legge (Lauren Versnick), a British performance artist
The host, “Lord James,” is based on Edward James, the wealthy English poet and collector who was one of Surrealism’s biggest backers. He sponsored Dalí, worked with him on the famous Mae West Lips Sofa and Lobster Telephone, and through Dalí met Magritte, who stayed at James’s London home in 1937 and painted two portraits of him. James’s West Dean estate in Sussex, where the show’s fictional party is loosely set, included Monkton House, which he decorated as a Surrealist showcase.
The real 1936 exhibition
The artists in the show are building up to the International Surrealist Exhibition, and that’s real. It ran from June 11 to July 4, 1936 at the New Burlington Galleries in Mayfair, London. Paul Nash sat on the English organising committee, Man Ray on the French one, and Mesens and Dalí represented Belgium and Spain. Magritte, Ernst, Picasso and many others showed work. About two thousand people came to the opening.
Two of its best-known moments involve characters in the series:
- Sheila Legge opened the show as the “Surrealist Phantom,” standing in Trafalgar Square in a white wedding dress with her head hidden behind roses.
- Dalí gave a lecture on July 1 in a deep-sea diving suit, and nearly suffocated before the poet David Gascoyne got the helmet off with a spanner.
What’s made up
The killings, the detectives’ investigation and the plot are all fiction, and so is the idea that any of these artists was ever a murder suspect. The real people lived on long after 1936. Sheila Legge, for example, died of pleurisy and pneumonia in France in 1949. The title is a joke too: it plays on Ceci n’est pas une pipe (“This is not a pipe”), the caption on Magritte’s 1929 painting The Treachery of Images.
